BuildOptions.BuildScriptsOnly

描述

仅在项目中构建脚本。

在使用 BuildScriptsOnly 之前，需要构建整个项目。然后，可以运行仅具有脚本更改的构建。

以下脚本示例便使用了 BuildScriptsOnly。该脚本最初会构建整个项目。在第一次运行脚本之后，可以使用该脚本仅编译脚本更改。要使用该脚本，请创建一个项目并在下面添加编辑器脚本和游戏脚本。

using UnityEditor;
using UnityEngine;

public class EditorExample : MonoBehaviour
{
    [MenuItem("Build/Build scripts")]
    public static void MyBuild()
    {
        BuildPlayerOptions buildPlayerOptions = new BuildPlayerOptions();
        buildPlayerOptions.scenes = new[] { "Assets/scene.unity" };
        buildPlayerOptions.locationPathName = "scriptBuilds";
        buildPlayerOptions.target = BuildTarget.StandaloneOSX;

        // use these options for the first build
        buildPlayerOptions.options = BuildOptions.Development;

        // use these options for building scripts
        // buildPlayerOptions.options = BuildOptions.BuildScriptsOnly | BuildOptions.Development;

        BuildPipeline.BuildPlayer(buildPlayerOptions);
    }
}

将以下简单脚本附加到场景中的空游戏对象：

using UnityEngine;

// Change the camera to the usual blue color and display a label.

public class ExampleClass : MonoBehaviour
{
    private Camera cam;

    void Awake()
    {
        cam = Camera.main;
        cam.clearFlags = CameraClearFlags.SolidColor;
    }

    void OnGUI()
    {
        GUI.Label(new Rect(100, 100, 100, 50), "ExampleClass");
    }
}

现在运行 Build/Build scripts 示例。这会构建一个可执行文件。运行该可执行文件，随后将显示带有标签的深蓝色窗口。接下来，在项目中添加一些立方体和球体。进行以下脚本更改：

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    private Camera cam;

    // added line
    private float delay;

    void Awake()
    {
        delay = 0.0f;
        cam = Camera.main;
        cam.clearFlags = CameraClearFlags.SolidColor;
    }

    // added script code
    void FixedUpdate()
    {
        delay = delay + Time.deltaTime;

        if (delay > 0.5f)
        {
            cam.backgroundColor = new Color(0.0f, 0.0f, Random.Range(0.0f, 0.25f));
            delay = 0.0f;
        }
    }

    void OnGUI()
    {
        GUI.Label(new Rect(100, 100, 100, 50), "ExampleClass");
    }
}

最后，交换 EditorExample 脚本中带注释的行：

using UnityEditor;
using UnityEngine;

public class EditorExample : MonoBehaviour
{
    [MenuItem("Build/Build scripts")]
    public static void MyBuild()
    {
        BuildPlayerOptions buildPlayerOptions = new BuildPlayerOptions();
        buildPlayerOptions.scenes = new[] { "Assets/scene.unity" };
        buildPlayerOptions.locationPathName = "scriptBuilds";
        buildPlayerOptions.target = BuildTarget.StandaloneOSX;

        // use these options for the first build
        // buildPlayerOptions.options = BuildOptions.Development;

        // use these options for building scripts
        buildPlayerOptions.options = BuildOptions.BuildScriptsOnly | BuildOptions.Development;

        BuildPipeline.BuildPlayer(buildPlayerOptions);
    }
}

使用 Build/Build scripts 重新生成应用程序，然后将其启动。该应用程序现在将显示背景颜色的随机变化。但是，添加的立方体和球体不可见。
